Description

BACKGROUND OF THE INVENTION

Field of the Invention

[0001] The present invention relates to an image capturing apparatus that performs image and voice recording.

Description of the Related Art

[0002] Conventionally, when a police officer is on patrol or the like using a vehicle, video is captured by a wearable camera worn by the police officer, and also the video is simultaneously captured by an on-vehicle camera mounted on the police vehicle driven by the police officer. In order to efficiently support an operation of the police officer, recording of the video by the wearable camera and the on-vehicle camera are needed to be performed in a coordinated manner.

[0003] Japanese Patent Laid-Open No. 2021-27408 discloses a camera system described below as a technique for recording by a wearable camera and an on-vehicle camera in a coordinated manner. The on-vehicle system includes an on-vehicle camera that can capture images of the surroundings of the vehicle, and an on-vehicle recorder that can record a first captured video captured by the on-vehicle camera. Subsequently, in response to receiving a predetermined alarm notification, recording of the first captured video to the on-vehicle recorder is started, and simultaneously the wearable camera is instructed to start recording of a second captured video. In response to the instruction to start recording, the wearable camera starts recording the second captured video and transmits the second captured video to the on-vehicle system. The on-vehicle system records, in the on-vehicle recorder, the first captured video and the second captured video in association with each other. Such an operation allows for coordinated recording of the video of the wearable camera and the on-vehicle camera.

[0004] Such a coordinated operation is important not only between cameras but also a case where the video is recorded by the camera and the voice is recorded by a microphone.

[0005] For example, let us consider a case of a system including a camera and a microphone that can wirelessly transmit voice to the camera, in which the camera has a video recording function, and also the microphone independently has a voice recording function. In this case, a case is conceivable that a state may happen in which the voice is recorded at the microphone side but the video is not recorded at the camera side when the coordination between the camera and the microphone may not successfully performed. On the contrary, there may arise a problem such that the video is recorded but the voice is not recorded. In addition, it is also conceivable that the start timings of recording the video at the camera side and recording the voice at the microphone side may deviate from each other.

SUMMARY OF THE INVENTION

[0006] The present invention has been made in view of the aforementioned problems, making it possible to perform recording of the image by the image capturing apparatus and recording of the voice by the microphone in good coordination, in a system including an image capturing apparatus and a microphone that can perform wireless communication.

[0016] Hereinafter, embodiments will be described in detail with reference to the attached drawings. Note, the following embodiments are not intended to limit the scope of the claimed invention. Multiple features are described in the embodiments, but limitation is not made to an invention that requires all such features, and multiple such features may be combined as appropriate. Furthermore, in the attached drawings, the same reference numerals are given to the same or similar configurations, and redundant description thereof is omitted.

(Basic Configuration of Image Capturing System)

[0017] FIG. 1 is a block diagram illustrating a configuration of an image capturing system 1000 according to an embodiment of the present invention.

[0018] Note that one or more of functional blocks illustrated in FIG. 1 may be implemented by hardware such as an ASIC and a programmable logic array (PLA), or may be implemented by causing a programmable processor such as a CPU and an MPU to execute software. The functional blocks may also be implemented by combination of software and hardware. Accordingly, in the following description, even when different functional blocks are described as operating subjects, the same hardware may be implemented as a subject.

[0019] In FIG. 1, an image capturing system 1000 includes a digital camera (referred to as camera, in the following) 1 and a wireless microphone 400 that can communicate with the camera 1. The camera 1 includes a camera body 100, a lens unit 200 attachable to and detachable from the camera body 100, and a voice reception unit 300 configured to wirelessly receive voice signals.

[0020] In the following, description will be provided assuming that the camera 1 is in a state where the lens unit 200 and the voice reception unit 300 are attached to the camera body 100. Although the present embodiment will be described for a case where the camera body 100, the lens unit 200, and the voice reception unit 300 are separate units, the camera 1 may have a configuration in which the camera body 100 and the lens unit 200 are integrated together. In addition, the camera body 100 and the voice reception unit 300 may be integrated together.

[0021] First, a configuration of the camera body 100 will be described. In FIG. 1, a camera control unit 101 includes, inside the camera control unit 101, a microcomputer (CPU) configured for controlling, and comprehensively controls operation of each unit in the camera 1. In addition, the camera control unit 101 also controls driving of an image sensor 106.

[0022] A shutter 104 includes light shielding members corresponding to a front curtain and a rear curtain of a so-called focal plane type, and controls the charge accumulation period in the image capturing element 106 by changing the light shielding state of the image sensor 106. A shutter driving unit 105 drives the shutter 104. Here, although the shutter 104 is used to control the exposure period when capturing a still image, it is left in an open state when a moving image is captured.

[0023] The image sensor 106 is a charge-storage-type solid-state image sensor such as a CMOS including a plurality of pixels that are so-called X-Y address type and two-dimensionally arranged. The image sensor 106 photoelectrically converts (performs image capturing of) light flux of a subject and outputs image data.

[0024] A captured image signal processing unit 107 performs various processing on image data output from the image sensor 106. For example, the captured image signal processing unit 107 performs amplification of image data, A/D conversion processing from analog image data to digital image data, various correction processing of the A/D-converted image data, compression processing into a predetermined compression format, or the like.

[0025] A timing generation unit 108 outputs various timing signals to the image sensor 106 and the captured image signal processing unit 107. A memory unit 111 can record data related to operation of the camera 1 and various data acquired by the camera 1. The memory unit 111 of the present embodiment includes a ROM area as a non-volatile memory, and a RAM area as a volatile memory.

[0026] A first storage medium control I/F unit 109 is an interface configured for recording of captured image data or moving image data, into a first storage medium 110, or reading of image data or moving image data, from the first storage medium 110. The first storage medium 110 including a semiconductor memory or the like is attachable to and detachable from the camera body 100 and records various data such as image data.

[0027] A display apparatus 103 includes a Thin Film Transistor driven type Liquid Crystal Display (TFT type LCD) or the like, and can display acquired still images or moving images. The display driving unit 102 causes the display apparatus 103 to display image data or the like.

[0028] A first video recording button 112 is a button that serves as a trigger (video recording instruction) of video recording of the moving image in the camera body 100. A user can input an instruction to start the video recording by pressing operation for the first video recording button 112. Upon detecting that the first video recording button 112 is pressed, the camera control unit 101 controls the lens unit 200, the image sensor 106, the captured image signal processing unit 107 or the like to capture the moving image. Simultaneously, the camera control unit 101 transmits a video recording start signal to a voice reception control unit 301 of the voice reception unit 300. The voice reception control unit 301 transmits the video recording start signal to a first wireless transmission and reception unit 302, and further, the first wireless transmission and reception unit 302 transmits the video recording start signal to the outside by a wireless radio wave.

[0029] Next, a configuration of the lens unit 200 will be described. In FIG. 1, a lens control unit 201 includes a microcomputer for lens (LCPU) inside the lens control unit 201, and controls operation of the lens unit 200. Here, the camera control unit 101 and the lens control unit 201 can communicate with each other via a terminal group provided on the camera body 100 side and a terminal group provided on the lens unit 200 side, in a state where the lens unit 200 is attached to the camera body 100.

[0030] An image capturing lens group 202 includes a focus lens, a shift lens, a zoom lens or the like, and guides the light flux of the subject toward the image sensor 106. A lens driving apparatus 203 drives the image capturing lens group 202 and drives the lens unit 200 such that, for example, a focal point of the focus lens may be brought into focus on the subject. A diaphragm 204 adjusts the amount of light from the subject guided into the camera 1 by the image capturing lens group 202. A diaphragm driving unit 205 drives the diaphragm 204.

[0031] Next, a configuration of the voice reception unit 300 will be described. The voice reception control unit 301 includes a microcomputer (CPU) for voice reception control inside the voice reception control unit 301, and controls the voice reception unit 300. Here, the camera control unit 101 and the voice reception control unit 301 can communicate with each other via a terminal group provided on the camera body 100 side and a terminal group provided on the voice reception unit 300 side, in a state where the voice reception unit 300 is attached to the camera body 100. In addition, the first wireless transmission and reception unit 302 of the voice reception unit 300 can wirelessly communicate with a second wireless transmission and reception unit 402 of the wireless microphone 400, which will be described below.

[0032] Next, a configuration of the wireless microphone 400 will be described. A voice transmission control unit 401includes a microcomputer (TMPU) for the control of the wireless microphone in the voice transmission control unit 401, and controls operation of the wireless microphone 400. Here, the second wireless transmission and reception unit 402 can wirelessly communicate with the first wireless transmission and reception unit 302 of the voice reception unit 300.

[0033] The microphone unit 403 collects, and converts into a voltage signal, ambient voice and voice of a person wearing the wireless microphone 400. A voice processing unit 404 performs processing such as a gain processing or a filtering processing on the converted voltage signal to convert the voltage signal into a digital voice signal. The voice transmission control unit 401 transmits the converted digital voice signal to the second wireless transmission and reception unit 402. The second wireless transmission and reception unit 402 transmits the digital signal to the outside by a radio wave.

[0034] A battery 407, which is a power source of the wireless microphone 400, supplies power to the voice transmission control unit 401 while a power source SW (not illustrated) is on.

[0035] A second video recording button 408 is a button that triggers the camera body 100 to perform the video recording of the moving image. When the voice transmission control unit 401 has detected that the second video recording button 408 is pressed, the voice transmission control unit 401 transmits an ON signal (video recording instruction signal) of the video recording button to the second wireless transmission and reception unit 402. The second wireless transmission and reception unit 402 transmits the ON signal of the video recording button to the outside by a wireless radio wave.

[0036] The second storage medium control I/F unit 405 is an interface configured for recording of collected voice data, into the second storage medium 406. The second storage medium 406 records the voice data as a backup, in a case in which the voice cannot be transmitted due to degradation of the radio wave state when the wireless microphone 400 is wirelessly transmitting the voice to the voice reception unit 300. The second storage medium 406 including a semiconductor memory or the like is attachable to and detachable from the wireless microphone 400, and records various data such as voice data.

[0037] While the voice data is being recorded in the second storage medium 406, an LED 409 lights up or blinks to inform the user that the voice recording is ongoing.

[0038] FIG. 2 is a diagram illustrating an appearance of the camera 1 in FIG. 1. The camera body 100 includes the first video recording button 112 that serves as a trigger for starting the video recording, and the display apparatus 103. FIG. 2 illustrates a state where the voice reception unit 300 is attached to the camera body 100. When the user presses the first video recording button 112, the camera 1 starts recording of the moving image (video recording).

[0039] FIG. 3 is a diagram illustrating an appearance of the wireless microphone 400 in FIG. 1. The microphone unit 403, the second video recording button 408, and the LED 409 configured for displaying voice recording are provided in the wireless microphone 400. By pressing the second video recording button 408, the camera starts recording of the moving image (video recording).

[0040] FIG. 4 is a schematic diagram illustrating an actual use state of the camera 1 and the wireless microphone 400. A person 500A and a person 500B are subjects to be captured by the camera 1. The person 500A and the person 500B respectively wear a wireless microphone 400A and a wireless microphone 400B, and collect their respective voices. The wireless microphone 400A and the wireless microphone 400B are wirelessly connected to the voice reception unit 300, and the collected voices of the person 500A and the person 500B are wirelessly transmitted to the voice reception unit 300. When the second video recording button 408 of at least one of the wireless microphone 400A and the wireless microphone 400B is pressed, the camera 1, which is wirelessly connected, starts the video recording of an image.

[0041] FIG. 5 is a diagram illustrating a communication flow when the person 500B has pressed the second video recording button 408 of the wireless microphone 400B, and FIGS. 6A and 6B are flowcharts illustrating the operation in this case. Referring to FIG. 5 and FIGS. 6A and 6B, processing performed when the person 500B has pressed the second video recording button 408 of the wireless microphone 400B will be described. In the following description of the flowchart, S indicates a step number.

[0042] S101, S121 and S 141 in FIGS. 6A and 6B indicate the starting of the flowcharts of each operation of the camera 1, the wireless microphone 400A, and the wireless microphone 400B. When the user powers on the camera 1, the wireless microphone 400A and the wireless microphone 400B at S102, S122, and S 142, operations of respective apparatuses are started.

[0043] Here, the operation is assumed for a case where the second video recording button 408 of the wireless microphone 400B is pressed, and therefore the following description will be provided assuming that the operation of the system is triggered by the pressing of the second video recording button 408 of the wireless microphone 400B. Noted that, in the following description, the voice transmission control unit 401 that is a control unit of the wireless microphone 400A will be referred to as a control unit 401A, and the voice transmission control unit 401 that is a control unit of the wireless microphone 400B will be referred to as a control unit 401B.

[0044] At S143, the control unit 401B determines whether or not the second video recording button 408 of the wireless microphone 400B is turned on. When the second video recording button 408 is OFF, the control unit 401B repeats the processing S 143, or advances the processing to S 144 when the second video recording button 408 is ON.

[0045] At S144, the control unit 401B wirelessly transmits the ON signal of the video recording button. This transmission corresponds to the communication A in FIG. 5.

[0046] In the camera 1, the camera control unit 101 determines at S 104 whether or not the ON signal of the video recording button transmitted from the wireless microphone 400B at S 144 is received. When the ON signal of the video recording button is received, the camera control unit 101 advances the processing to S105, or repeats the operation of S 104 when the ON signal of the video recording button is not received.

[0047] At S105, the camera control unit 101 wirelessly transmits a video recording start signal via the first wireless transmission and reception unit 302 of the voice reception unit 300. This transmission corresponds to the communication B illustrated in FIG. 5. Note that, when the remaining capacity of the first storage medium 110 is not enough for recording images or such cases, the operation of the camera 1 is terminated without transmitting the video recording start signal.

[0048] At S125 and S145, the control unit 401A of the wireless microphone 400A and the control unit 401B of the wireless microphone 400B determine whether or not the video recording start signal transmitted from the camera 1 at S105 is received. When the video recording start signal is received, the control unit 401A and the control unit 401B respectively advance the processing to S126 and S 146, or respectively repeat the processing S 125 and S 145 when the video recording start signal is not received.

[0049] At S 126 and S146, the control unit 401A and the control unit 401B start the voice recording by the wireless microphone 400A and the wireless microphone 400B. In addition, at S106, the camera control unit 101 starts the video recording of the moving image being captured by the camera 1. Note that, at this time, the voice is wirelessly transmitted from the wireless microphone 400A and the wireless microphone 400B to the camera 1, and therefore the voice is also recorded in the first storage medium 110 with the moving image.

[0050] By the aforementioned operation, the video recording of the moving image captured by the camera 1 and the voice recording of the voice collected by the wireless microphone 400A and the wireless microphone 400B are synchronously started. Next, an operation of synchronously stopping the video recording and the voice recording will be described.

[0051] At S147, the control unit 401B determines whether or not the second video recording button 408 of the wireless microphone 400B is pressed. When the second video recording button 408 is pressed, the control unit 401B advances the processing to S148, or repeats the processing S147 when the second video recording button 408 is not pressed.

[0052] At S148, the control unit 401B wirelessly transmits the ON signal of the video recording button. This transmission corresponds to the communication A illustrated in FIG. 5.

[0053] At S108, the camera control unit 101 determines whether or not the ON signal (stop instruction signal) of the video recording button transmitted from the wireless microphone 400B at S148 is received. When the ON signal of the video recording button is received, the camera control unit 101 advances the processing to S109, or repeats the operation S108 when the ON signal of the video recording button is not received.

[0054] At S109, the camera control unit 101 wirelessly transmits a video recording stop signal via the first wireless transmission and reception unit 302 of the voice reception unit 300. This transmission corresponds to the communication B illustrated in FIG. 5.

[0055] At S129 and S149, the control unit 401A of the wireless microphone 400A and the control unit 401B of the wireless microphone 400B determine whether or not the video recording stop signal transmitted from the camera 1 at S109 is received. When the video recording stop signal is received, the control unit 401A and the control unit 401B respectively advance the processing to S130 and S150, or respectively repeat the processing S129 and S149 when the video recording stop signal is not received.

[0056] At S130 and S150, the control unit 401A and the control unit 401B terminate the voice recording by the wireless microphone 400A and the wireless microphone 400B. In addition, at S110, the camera control unit 101 stops the video recording of the moving image captured by the camera 1.

[0057] When the user turns off each of the power sources of the camera 1, the wireless microphone 400A and the wireless microphone 400B at S111, S131 and S151, operations of the camera 1, the wireless microphone 400A and the wireless microphone 400B are terminated.

[0058] As has been described above, in the present embodiment, a video recording start signal is transmitted from the camera to the wireless microphone after the camera is instructed to start the video recording. The wireless microphone starts the voice recording of the voice at the timing of receiving the video recording start signal. Accordingly, the wireless microphone can perform the voice recording at substantially the same timing as the video recording by the camera.

[0059] Although the present embodiment has been described for a case of using two wireless microphones, similar processing can be performed using one or more wireless microphones. In addition, although the present embodiment has been described to start and stop the video recording using the wireless microphone B, it is also possible to start the video recording using one of the plurality of wireless microphones and stop the video recording using another one of the plurality of wireless microphones.

[0060] Next, FIG. 7 is a diagram illustrating a communication flow when the user presses the first video recording button 112 provided on the camera body 100, and FIGS. 8A and 8B are flowcharts illustrating the operation in this case. Referring to FIG. 7 and FIGS. 8A and 8B, processing performed when the user presses the first video recording button 112 will be described.

[0061] S201, S221 and S241 in FIGS. 8A and 8B indicate the start of the flowcharts of respective operations of the camera 1, the wireless microphone 400A and the wireless microphone 400B. When the user powers on the camera 1, the wireless microphone 400A and the wireless microphone 400B at S202, S222 and S242, operations of respective apparatuses are started.

[0062] Here, the operation is assumed for a case where the first video recording button 112 of the camera body 100 is pressed, and therefore the following description will be provided assuming that operation of the system is triggered by pressing the first video recording button 112 of the camera body 100. Noted that, in the following description, the voice transmission control unit 401 that is a control unit of the wireless microphone 400A will be referred to as a control unit 401A, and the voice transmission control unit 401 that is a control unit of the wireless microphone 400B will be referred to as a control unit 401B.

[0063] At S204, the camera control unit 101 determines whether or not the first video recording button 112 is turned on. When the first video recording button 112 is OFF, the camera control unit 101 repeats the processing S204, or advances the processing to S205 when the first video recording button 112 is ON.

[0064] At S205, the camera control unit 101 wirelessly transmits a video recording start signal via the first wireless transmission and reception unit 302 of the voice reception unit 300. This transmission corresponds to the communication B in FIG. 7. Note that, when the remaining capacity of the first storage medium 110 is not enough for recording images or such cases, the operation of the camera 1 is terminated without transmitting the video recording start signal.

[0065] At S225 and S245, the control unit 401A of the wireless microphone 400A and the control unit 401B of the wireless microphone 400B determine whether or not the video recording start signal transmitted from the camera 1 at S205 is received. When the video recording start signal is received, the control unit 401A and the control unit 401B respectively advance the processing to S226 and S246, or respectively repeat the processing S225 and S245 when the video recording start signal is not received.

[0066] At S226 and S246, the control unit 401A and the control unit 401B start the voice recording of the voice by the wireless microphone 400A and the wireless microphone 400B. In addition, at S206, the camera control unit 101 starts the video recording of the moving image captured by the camera 1. Note that, at this time, the voice is wirelessly transmitted from the wireless microphone 400A and the wireless microphone 400B to the camera 1, and therefore the voice is also recorded in the first storage medium 110 together with the moving image.

[0067] By the aforementioned operation, the video recording of the moving image captured by the camera 1 and the voice recording of the voice collected by the wireless microphone 400A and the wireless microphone 400B are synchronously started. Next, an operation of synchronously stopping the video recording and the voice recording will be described.

[0068] At S208, the camera control unit 101 determines whether or not the first video recording button 112 is pressed. When the first video recording button 112 is pressed, the camera control unit 101 advances the processing to S209, or repeats the processing S208 when the first video recording button 112 is not pressed.

[0069] At S209, the camera control unit 101 wirelessly transmits a video recording stop signal via the first wireless transmission and reception unit 302 of the voice reception unit 300. This transmission corresponds to the communication B illustrated in FIG. 7.

[0070] At S229 and S249, the control unit 401A of the wireless microphone 400A and the control unit 401B of the wireless microphone 400B determine whether or not the video recording stop signal transmitted from the camera 1 at S209 is received. When the video recording stop signal is received, the control unit 401A and the control unit 401B respectively advance the processing to S230 and S250, or respectively repeat the processing S229 and S249 when the video recording stop signal is not received.

[0071] At S230 and S250, the control unit 401A and the control unit 401B stop the voice recording of the voice by the wireless microphone 400A and the wireless microphone 400B. At S210, the camera control unit 101 stops the video recording of the moving image captured by the camera 1.

[0072] When the user turns off each of the power sources of the camera 1, the wireless microphone 400A and the wireless microphone 400B at S211, S231 and S251, operations of the camera 1, the wireless microphone 400A and the wireless microphone 400B are terminated.

[0073] As has been described above, in the present embodiment, the video recording start signal is transmitted from the camera to the wireless microphone. The wireless microphone starts the voice recording of the voice at the timing of receiving the video recording start signal. Accordingly, the wireless microphone can perform the voice recording at substantially the same timing as the video recording by the camera.

[0074] Although the present embodiment has been described for a case of using two wireless microphones, similar processing can be performed using one or more wireless microphones.
